Functional Group
Interconnect system comprising wires and connectors enclosed in protective coverings designed to link sensors to a central processing unit. Every sensor harness assembly must provide reliable electrical pathways while withstanding environmental stresses. This unit functions as the nervous system for industrial machinery and vehicles.
Mechanical Protection
Braided sleeves or corrugated tubes shield the internal conductors from abrasion and chemical exposure. A sensor harness assembly often includes strain relief features at the connector interface to prevent wire fatigue. Design choices for the outer jacket depend on the specific fluids and temperatures present in the application.
Electrical Shielding
Integrity of the signal requires protection from electromagnetic interference through foil or braided layers. The sensor harness assembly must maintain shield continuity from the sensor body to the control module. Grounding points are strategically placed to prevent ground loops that could introduce offset errors in analog measurements.
Routing is managed away from high-current power lines. In many automotive applications, the harness is subjected to rigorous vibration testing to ensure that the terminals do not experience fretting corrosion over time.
Qualification Standard
Continuity and insulation resistance tests verify the manufacturing quality of each unit. A custom sensor harness assembly undergoes functional checks to confirm that the pinout matches the system schematic.
